Description

Item holograms fall to the ground.
After creating item hologram through BetonQuest, I've discovered that the items fall to the ground after a while. I have now tried it directly through HD and not using beton, still happens for us. We assume it's a plugin mis-match and something to do the areas being unloaded and then loaded.
It could take up to 20min after loading up before we discover a item hologram fallen to the ground.

How to reproduce

So far we've tried everything we can think of + devs from the Beton team have tried and we can not report a 100% safe reproduction step by step.

Additional context

We have tried disabling plugin after plugin and are not yet successful in finding what it could be, it takes a while for the bug to appear at times.
